以煤矿瓦斯爆炸险兆事件为研究对象,运用文献综述与现场访谈的方法对其影响因素进行了归纳总结,并运用问卷调查的方法对这些因素的准确性进行了验证;然后运用解释结构模型对影响因素进行了分层,明确了煤矿瓦斯爆炸险兆事件的致因机理。研究结果表明:煤矿瓦斯爆炸险兆事件影响因素分为4类二级指标与20个三级指标;20个三级指标通过不同层级的作用关系,影响着煤矿瓦斯爆炸险兆事件的发生,表层因素中6个因素是影响险兆事件发生的直接原因,中层因素中11个因素是间接原因,深层因素中3个因素是根本原因。
Taking the coal mine gas explosion danger event as the research object, this paper summarizes the influencing factors by means of literature review and on-the-spot interview, and verifies the accuracy of these factors by means of questionnaire. Then, The influencing factors were stratified, and the cause mechanism of the coalmine gas explosion danger event was clarified. The results show that the influencing factors of coal mine gas explosion danger events are divided into four kinds of second-level indicators and twenty third-level indicators; 20 third-level indicators affect the occurrence of gas explosion danger events in coal mine through the interaction of different levels, Six of the factors are the direct reasons that affect the occurrence of risk events. Eleven of the middle-level factors are indirect reasons and three of the deep-rooted factors are the root causes.
